He also stated that he would like to welcome Google into "Microsoft's world," apparently referring to the mobile phone market.

He said, "Right now they have a press release, we have many, many millions of customers, great software, many hardware devices and they're welcome in our world."

His remarks seem slightly curious as Microsoft is dominated in market share of the mobile phone market by the more widespread Symbian OS.

Ballmer refused to comment on the Android software itself, instead simply sticking to a general critique of Google policy. He said that he felt that Android OS was vaporware at the present and could not be compared to Microsoft's mobile phone OS, Windows Mobile.

"Well of course their efforts are just some words on paper right now, it's hard to do a very clear comparison [with Windows Mobile]," he said.

Ballmer says he is not threatened by Google, but that Microsoft is watching them like a hawk.

"So we have great momentum, we've brought our Windows Mobile 6 software to market, we're driving forward on our future releases and we'll have to see what Google does," said Ballmer.

Google's Android OS is based on Linux and is under a modified open-source Apache license. It is being co-developed by "the Open Handset Alliance," which includes industry giants such as T-Mobile, Sprint Nextel, Samsung Electronics, and LG Electronics.

Whether Android OS will be a hit or miss remains to be seen, but it appears to be making competitors slightly antsy and generating some new interesting comments to add to Microsoft's colorful public relations history.
